CHECK RIGID LINK

 

Description: This function checks the connectivity and length of all rigid elements, RBE2 and RBAR. Rigid bodies that exceed the length criteria of the user or that are loose, zero-length, double dependent, cyclic, or redundant are highlighted.

 

Usage:

                       

 1.   DSI prompts:

>       FIND RIGID LINKS LONGER THAN CERTAIN LENGTH? (Y/N)

?       YES

>       ENTER LENGTH CRITERIA

•            Any real number greater than zero.

  NO

 

 2.    The user has the option to place failed elements into new parts.  If the user opts to place the failed elements into a new part, DSI will generate the following part names:

r.xlong          • Checks for RBE2s that fail length check.

r.duplic         • Checks for degenerate RBE2s.

r.cyclic          • Checks for two RBE2s sharing the same two nodes in an independent/dependent node loop.

r.double        • Checks for RBE2s with double dependent nodes.

r.loose          • Checks for loose connections.

 

The user returns to the MODEL CHECKER menu
